Pharmacokinetic and pharmacodynamic changes in older adults and implications for palliative care

Background: As the population of older adults continues to increase, there will be an increase in the number of older patients requiring pain and symptom management in the setting of advanced, serious illness.

Objectives: To review age-related changes in pharmacokinetics and pharmacodynamics, and to put these changes in the context of providing palliative care to geriatric patients.

Method: Review of literature relevant to age-related changes in physiology, pharmacokinetics, and pharmacodynamics; and the practice of palliative care for geriatric patients.

Results: Multiple age related changes occur which affect the choice and dosing of medications, including those used for pain and symptom management.

Conclusion: The safe and effective management of symptoms in advanced illness for older adults depends on having a clear understanding of physical and metabolic changes and their impact of selection of drug therapy.     

Patient trajectories in a Norwegian unit of municipal emergency beds

Objective: The Coordination reform was implemented in Norway from 2012, aiming at seamless patient trajectories. All municipalities are required to establish emergency care beds (MEBs) to avoid unnecessary hospital admissions. We aimed to examine occupancy rate, patient characteristics, diagnoses and discharge level of municipal care in a small MEB unit.

Design: Cross-sectional, observational study.

Setting: A two-bed emergency care unit.

Subjects: All patients admitted to the unit during one year.

Main outcome measures: Patients’ age and gender, comorbidity, main diagnoses and municipal care level on admission and discharge, diagnostic and therapeutic initiatives, occupancy rate.

Results: Sixty admissions were registered, with total bed occupancy 194 days, and an occupancy rate of 0.27. The patients (median age 83 years, 57% women) had mostly infections, musculoskeletal symptoms or undefined conditions. Some 48% of the stays exceeded three days and 43% of the patients were subsequently transferred to nursing homes or hospitals.

Conclusion: Occupancy rate was low. Patient selection was not according to national standards, and stays were longer. Many patients were transferred to nursing homes, indicating that the unit was an intermediate pathway or a short cut to institutional care. It is unclear whether the unit avoided hospital admissions.     

Factors associated with self-rated health in primary care

Background: Self-rated health (SRH) measures one’s current general health and is a widely used health indicator. Sleep problems, somatic health complaints, and unmet needs in interpersonal relationships are suspected to influence SRH, but studies in primary health care settings are sparse.

Objective: To examine the associations between patients’ self-rated health and their sleep problems, somatic health complaints, and unmet needs in interpersonal relationships.

Design: We collected data via questionnaires for this cross-sectional study from general practice.

Setting: Primary health care in Norway.

Subjects: 1302 consecutive patients participated.

Main outcome measures: The questionnaire included a single question about SRH, the Bergen Insomnia Scale (BIS), five questions on somatic health complaints, and three questions from the Basic Psychological Needs Scale (BPNS) pertaining to the relationships domain. We analyzed our data using ordinal logistic regression models.

Results: Our response rate was 74%. The prevalence of fair/poor SRH was 26%, with no gender differences. We revealed a significant association between increasing age and reduced SRH. The study showed that sleep problems and somatic health complaints were strongly associated with SRH, and unmet needs in relationships were also significantly and independently associated with reduced SRH in a full model analysis.

Conclusion: Sleep problems, somatic health complaints, and unmet needs in interpersonal relationships were all associated with reduced SRH. These factors are all modifiable and could be managed both within and outside a primary care setting in order to improve SRH.

• Key Points

• There was a high prevalence of reduced SRH in clinical general practice

• Sleep problems, somatic health complaints, and unmet needs in interpersonal relationships were all associated with reduced SRH

• These predictors are all modifiable with a potential to improve SRH

     

A double-blind placebo-controlled clinical investigation into pain reduction effect of placing the pain spot outside the intersection area of the two currents of interferential therapy compared to traditional method

Background: Interferential therapy (IFT) is applied to intersect in the painful area but no confirmed effect with this method. Experimentally, the highest voltage of IFT is induced outside the intersection of the two currents. Placing the painful area outside the intersection point (external application) would reveal a better effect.

Objectives: To examine the effect of external application in pain compared to traditional method.

Design: A double-blind placebo-controlled clinical investigation.

Setting: A public hospital.

Participants: 168 LBP subjects.

Interventions: Assignment: (1) external IFT, (2) placebo external IFT, (3) traditional IFT and (4) placebo traditional IFT. Groups 1 and 3 received 20 min of IFT at 100 Hz and groups 2 and 4 received sham IFT.

Main outcome measures: Before and after IFT session, pain severity (VAS), pressure threshold (PPT), pain distribution and ROM were assessed.

Results: IFT changed all outcomes similarly. VAS and ROM improved statistically, P < 0.03. A trend of better VAS reduced with active IFTs.

Conclusions: No therapeutic difference between the two methods.     

Social disparities in diabetes care: a general population study in Denmark

Objective: We investigated the association between socioeconomic factors and the attainment of treatment goals and pharmacotherapy in patients with type 2 diabetes in Denmark.

Design: A cross-sectional population study.

Setting: The municipality of Naestved, Denmark.

Subjects: We studied 907 patients with type 2 diabetes identified from a random sample of 21,205 Danish citizens.

Main outcome measures: The proportion of patients who were not achieving goals for diabetes care based on their HbA_1c, LDL-cholesterol, blood pressure, and lifestyle, and the proportion of patients who were treated with antihypertensive and cholesterol- and glucose-lowering medication.

Methods: We investigated the association of the socioeconomic factors such as age, gender, education, occupation, income, and civil status and attainment of treatment goals and pharmacotherapy in logistic regression analyses. We investigated effect modification of cardiovascular disease and kidney disease.

Results: Middle age (40–65 years), low education level (i.e. basic schooling), and low household income (i.e. less than 21,400 € per year) were associated with nonattainment of goals for diabetes care. The association of socioeconomic factors with attainment of individual treatment goals varied. Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure. Socioeconomic factors were not associated with treatment goals for hyperglycemia. Socioeconomic factors were inconsistently associated with pharmacotherapy. There was no difference in contacts to general practitioners according to SES.

Conclusions: In a country with free access to health care, the socioeconomic factors such as middle age, low education, and low income were associated with nonattainment of goals for diabetes care.

• KEY POINTS

• Middle age, low education, and low income were associated with nonattainment of goals for diabetes care, especially for lifestyle goals.

• Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure.

• Association of socioeconomic factors with pharmacotherapy was inconsistent.

     

The creation of the diagnostic accuracy quality scale (DAQS)

Background:

The utility of a dedicated clinical test is dependent on the diagnostic accuracy values and the quality of the study in which the test was examined. Scales allow a summative scoring of bias within a study. At present, there are no scales advocated to measure the bias of diagnostic accuracy studies.

Objective:

The objective of this study was to create a new diagnostic accuracy quality scale (DAQS) that provides a quantitative summary of the methodological quality of studies evaluating clinical tests and measures.

Design:

The study used a four-round Delphi survey designed to create, revise, and develop consensus for a quality scale.

Methods:

The four-round Delphi involved a work team and a respondent group of experts. An initial round among the work team created a working document, which was then modified and revised, with opportunities to create new items threaded in the second round. Rounds III and IV involved voting on the importance of each of the proposed items and consensus development from the respondent group. Consensus for the selection of an item required a 75% approval for the importance of that item.

Results:

Sixteen individuals with a variety of research/professional backgrounds made up the respondent group. Modification and revision of the initial work team instrument created a scale with 21 items that reflected potential areas of methodological bias.

Limitations:

The new scale needs validation through weighted assessment. In addition, there was a large proportion of physical therapist/researchers on the work team and the respondent group.

Conclusions:

Systematic reviews allow summation of evidence for clinical tests and scales are essential to critique the quality of the articles included in the review. The DAQS may serve this role for diagnostic accuracy studies.     

Repetition of intentional drug overdose: a population-based study

Context: Intentional overdose is a leading method of self-harm and suicide, and repeat attempts strongly predict eventual death by suicide.

Objectives: To determine the risk of recurrence after a first intentional overdose. Secondary objectives included characterization of the temporal course and potential predictors of repeat overdose, a strong risk factor for death from suicide.

Methods: Design: Population-based cohort study.

Setting: Ontario, Canada, from 1 April 2002 to 31 March 2013.

Participants: All Ontario residents presenting to an emergency department after a first intentional overdose.

Main outcome measures: The incidence and timing of recurrent overdose.

Results: We followed 81,675 patients discharged from hospital after a first intentional overdose. Overall, 13,903 (17.0%) returned with a repeat overdose after a median interval of 288 (inter-quartile range: 62 to 834) days. Of these, 4493 (5.5%) had multiple repeat episodes. Factors associated with repeat self-poisoning included psychiatric care in the preceding year (adjusted hazard ratio [aHR] 1.55; 95% confidence interval [CI] 1.50 to 1.61), alcohol dependence (aHR 1.41; 95% CI 1.35 to 1.46) and documented depression (aHR 1.39; 95% CI 1.34 to 1.44). Female sex, rural residence, lower socioeconomic status, ingestion of psychoactive drugs and younger age were also weakly associated with repeat overdose.

Discussion: Hospital presentation for repetition of intentional overdose is common, with recurrent episodes often far removed from the first. While several factors predict overdose repetition, none is particularly strong.

Conclusion: Secondary prevention initiatives should be implemented for all individuals who present to the emergency department and survive intentional overdose.     

Learning to navigate the healthcare system in a new country: a qualitative study

Objective: Learning to navigate a healthcare system in a new country is a barrier to health care. Understanding more about the specific navigation challenges immigrants experience may be the first step towards improving health information and thus access to care. This study considers the challenges that Thai and Filipino immigrant women encounter when learning to navigate the Norwegian primary healthcare system and the strategies they use.

Design: A qualitative interview study using thematic analysis.

Setting: Norway.

Participants: Fifteen Thai and 15 Filipino immigrant women over the age of 18 who had been living in Norway at least one year.

Results: The women took time to understand the role of the general practitioner and some were unaware of their right to an interpreter during consultations. In addition to reliance on family members and friends in their social networks, voluntary and cultural organisations provided valuable tips and advice on how to navigate the Norwegian health system. While some women actively engaged in learning more about the system, they noted a lack of information available in multiple languages.

Conclusions: Informal sources play an important role in learning about the health care system. Formal information should be available in different languages in order to better empower immigrant women.     

Palliative care service in Cyprus,a population-based needs assessment based on routine mortality data

Background: Cyprus is currently forming its public healthcare system aiming to accompany people from cradle to grave. This population-based palliative care service needs assessment was performed under increasing demographic, economic, and societal pressures.

Objectives: The primary aim was to assess the palliative care service needs in Cyprus using routine mortality data and this was achieved by: (a) analysis of mortality death registration statistics making inferences to palliative care needs; (b) reviewing existing palliative care service provision in Cyprus.

Methods: Data derived from death registrations from January 2011 to December 2013 were analysed using specific International Classification of Diseases and Related Health Problems –10th Revision codes. The method developed by Rosenwax and Murtagh with further refinement of the disease categorisations was used to give a population-based estimate of palliative care needs at a minimum and at a maximum value, combined with symptom prevalence.

Results: Out of the 5500 people on average dying in Cyprus annually, a minimum 2634 and a maximum 3927 could benefit from a palliative care service. Palliative care provision in Cyprus today focuses almost exclusively on cancer, depending largely on philanthropic funding with some services being reduced despite evidence of increasing need.

Conclusion: Palliative care should be integrated into the public healthcare system with appropriate resource allocation. Recommendations are made to facilitate this.     

Yoga for pain and sleep quality in rheumatoid arthritis: study protocol for a pilot randomized controlled trial

Background:

Yoga is a popular complementary and alternative medicine (CAM) therapy among people with rheumatoid arthritis (RA), perceived as offering self-management options for physical and psychosocial symptoms associated with RA.

Objectives:

The primary aims of the current pilot study are (1) to assess the feasibility and safety of a relaxation-focused yoga intervention tailored for people with RA and (2) to estimate the effect of yoga on RA-related pain, sleep quality, functional disability, disease activity, quality of life, anxiety, depression, and fatigue.

Method:

Twenty-eight participants with at least minimum levels of RA-related pain and sleep disturbance will be recruited from a local public hospital database. Participants meeting inclusion criteria will be randomized into either a yoga group (receiving an 8-week program of once-weekly 75-minute relaxation-based yoga classes and thrice-weekly home practice), or a usual care control group. Outcomes will be assessed at baseline, 9, and 12 weeks. Feasibility is operationalized as acceptability (recruitment, adherence, participant retention, and participant satisfaction) and safety of the yoga intervention. Effect sizes for changes in pain, sleep quality, functional disability, disease activity, quality of life, mental health, and fatigue will be estimated.

Discussion:

Results of this pilot study will provide empirical data to determine if a larger, statistically powered main trial is feasible and safe in a national RA population. Additionally, participant feedback will provide information regarding further adaption and tailoring of the study protocol to a clinical RA population.

Pain pattern classification and directional preference for patients with neck pain

Objectives:

Pain Pattern Classification (PPC) and Directional Preference (DP) have been shown to be predictive of health care outcomes and serve to guide orthopedic clinical decision making. We conducted a prospective, observational cohort study to verify the association between PPC, DP, and clinical outcomes.

Methods:

Clinical outcome measures including pain intensity and disability were completed at first examination and follow-up by 335 patients. A Pearson’s chi-squared test was used to determine differences in prevalence rates for the categorical variables, and two-sample t-tests were used to determine differences in rates for the continuous variables. A Tukey’s range test was used to determine differences in follow-up pain intensity and disability for neck pain dual-classification schemes.

Results:

The prevalence of DP was 82.4%. The prevalence of CEN, Non-CEN, and Non-Classifiable (NC) was 15.2%, 42.1%, and 25.1%, respectively. The prevalence of DP was lowest for patients with sub-acute symptoms and who were <45 years old. Patients classified as DP CEN had, on average 2.62 NDI units less than patients classified as Non-DP. Patients classified as DP CEN had, on average, 0.90 pain intensity units less than patients classified as Non-DP at follow-up. Patients who demonstrated DP CEN did not have clinically significant lower pain intensity or disability at follow-up than patients who demonstrated Non-DP.

Discussion:

The results of this investigation need to be interpreted with caution with respect to the study design and it’s subsequent strengths and limitations.

Association between continuity of care in Swedish primary care and emergency services utilisation: a population-based cross-sectional study

Objective: The primary objective of this study was to determine the association between longitudinal continuity of care (CoC) in Swedish primary care (PC) and emergency services (ES) utilisation.

Study design: A cross-sectional analysis of longitudinal population data. Setting. PC centres, out-of-hours PC facilities and emergency departments (EDs) in Blekinge County in southern Sweden. Subjects: People of all ages who lived in Blekinge County and who had made two or more visits per year to a general practitioner (GP) during office hours from 1 January 2012 to 31 December 2014.

Main outcome measure: ES utilisation.

Results: Eight-thousand one-hundred and eighty-five people were included in the study. CoC was quantified using three different indices—Usual Provider of Care index (UPC), Continuity of Care index (CoCI), and Sequential Continuity index (SECON). The CoC that the PC centres could offer their enrolled patients varied significantly between the different centres, ranging from 0.23–0.57 for UPC, 0.12–0.43 for CoCI, and 0.25–0.52 for SECON. Association between the three CoC indices and ES utilisation was computed as an incidence rate ratio which ranged between 0.50 and 0.59.

Conclusion: Longitudinal CoC was shown to have a negative association with ES utilisation. The association was significant and of a magnitude that implies clinical relevance. Computed incidence rate ratios suggest that patients with the lowest CoC had twice as many ES visits compared to patients with the highest CoC.     

Translational manipulation under anesthesia for patients with frozen shoulder: a case series study with five-year health care utilization and post-manipulative arthroscopic findings

Study Design: Case series study.

Objectives: Although there have been no reported complications from translational manipulation under anesthesia (tMUA) for individuals with adhesive capsulitis (AC) there are no cases reporting surgical findings post tMUA. Also, there are no studies evaluating health care utilization following tMUA. The purpose of this study was to: (1) report clinical outcomes following tMUA, (2) describe relevant health care costs and utilization following tMUA, and (3) summarize findings from two cases receiving joint arthroscopy following tMUA.

Methods: Fourteen Individuals with AC underwent tMUA. Range of motion (ROM) and Shoulder Pain and Disability Index (SPADI) values were collected at baseline and six weeks follow-up. Shoulder-related health care cost and utilization were analyzed for a five-year period following tMUA. Two additional patients with AC underwent tMUA followed by arthroscopic assessment for evidence of iatrogenic injury.

Results: Thirteen patients completed the six-week follow-up. Mean change scores for ROM and SPADI values were flexion; +38.5°, abduction; +71.1°, external rotation (shoulder abducted); +49.8°, internal rotation (shoulder abducted); +26.6°, SPADI scores; +44.4. 13 patient records were analyzed for health care utilization. Ten of the 13 patients utilized no additional shoulder-related health care. Surgical evaluation revealed no evidence of iatrogenic injury.

Discussion: Clinical outcomes were similar to previous studies. Utilization data indicated that for the majority of patients, little shoulder-related health care was utilized. Surgical evaluation provided further evidence that tMUA performed by a physical therapist is safe. Future research will be required to establish a causal relationship between tMUA and the results observed in this study.

Level of Evidence: Therapy, Level 4.     

Quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections in general practice: a RAND Appropriateness Method

Objective: To develop quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections, tailored to the Danish general practice setting.

Design: A RAND/UCLA Appropriateness Method was used.

Setting: General practice.

Subjects: A panel of nine experts, mainly general practitioners, was asked to rate the relevance of 64 quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections based on guidelines. Subsequently, a face-to-face meeting was held to resolve misinterpretations and to achieve consensus.

Main outcome measures: The experts were asked to rate the indicators on a nine-point Likert scale. Consensus of appropriateness for a quality indicator was reached if the overall panel median rating was 7–9 with agreement.

Results: A total of 50 of the 64 proposed quality indicators attained consensus. Consensus was achieved for 12 indicators focusing on the diagnostic process and 19 indicators focusing on the decision about antibiotic treatment and choice of antibiotics, respectively.

Conclusion: These newly developed quality indicators may be used to strengthen Danish general practitioners’ focus on their management of patients with acute respiratory tract infections and to identify where there is a need for future quality improvements.     

Faecal immunochemical tests for the diagnosis of symptomatic colorectal cancer in primary care: the benefit of more than one sample

Objective: Faecal immunochemical tests (FITs) are used to screen for colorectal cancer (CRC) and as diagnostic aids in symptomatic patients. However, the number of samples per FIT varies. It is unclear if there is any advantage to analyse multiple-sample FITs in symptomatic patients.

Design and setting: This is a post hoc analysis of a retrospective study that included all cases of CRC and adenomas with high-grade dysplasia (HGD) between 2005 and 2009 in the county of Jämtland, Sweden.

Subjects: All patients with CRC and adenomas with HGD that initially presented with symptoms to primary care and delivered FITs.

Main outcome measure: The likelihood of a positive FIT in cases of CRC and adenomas with HGD; when analysing one, two or three samples.

Results: Of 195 patients, 160 delivered three-sample FITs. Using the 139 cases in which at least one sample was positive, the likelihood of detecting a positive sample upon analysis of only one of the three samples was 0.91 (95% CI: 0.85–0.95), indicating that 13 positive cases may have been missed.

Conclusion: Use of a one-sample FIT instead of a three-sample FIT as a diagnostic aid may result in the missing of one tenth of symptomatic CRCs and adenomas with HGD.     

Characteristics of community palliative care patients requiring acute admission to hospital

Background: A substantial proportion of palliative care patients cared for in the community require acute hospital admission during their terminal illness. A greater understanding of the multifactorial reasons leading to acute admission to hospital may enable some potential hospital admissions to be avoided through provision of appropriate community palliative care support.

Aim: To identify the characteristics of community specialist palliative care team (CSPCT) patients requiring acute admission to hospital.

Methods: A retrospective audit of all patients known to the CSPCT who required acute admission to hospital over a five-month period between January and June 2016.

Results: A total of 97 hospital admissions occurred, involving 88 patients. The majority of patients had a malignant diagnosis (80%) with 31% still undergoing anti-neoplastic therapy. Of these admissions, 58% were to acute hospital facilities and 42% were to hospital-based palliative care units. The leading reasons for hospitalization were pain (27%), patient/relative distress (24%) and dyspnoea (16%).

Conclusion: This study described the characteristics of CSPCT patients who required acute admission to hospital. Further research is needed to understand the reasons patients seek acute hospital admission and to explore if interventions in the community can decrease the rate of acute hospital admissions.     

Drug-related problems and changes in drug utilization after medication reviews in nursing homes in Oslo,Norway

Objective: We describe the drug-related problems (DRPs) identified during medication reviews (MRs) and the changes in drug utilization after MRs at nursing homes in Oslo, Norway. We explored predictors for the observed changes.

Design: Observational before-after study.

Setting: Forty-one nursing homes.

Intervention: MRs performed by multidisciplinary teams during November 2011 to February 2014.

Subjects: In all, 2465 long-term care patients.

Main outcome measures: DRPs identified by explicit criteria (STOPP/START and NORGEP) and drug–drug interaction database; interventions to resolve DRPs; drug use changes after MR.

Results: A total of 6158 DRPs were identified, an average of 2.6 DRPs/patient, 2.0 for regular and 0.6 for pro re nata (prn) drugs. Of these patients, 17.3% had no DRPs. The remaining 82.7% of the patients had on average 3.0 DRPs/patient. Use of unnecessary drugs (43.5%), excess dosing (12.5%) and lack of monitoring of the drug use (11%) were the most frequent DRPs. Opioids and psychotropic drugs were involved in 34.4% of all DRPs. The mean number of drugs decreased after the MR from 6.8 to 6.3 for regular drugs and from 3.0 to 2.6 for prn drugs. Patients with DRPs experienced a decrease of 1.1 drugs after MR (0.5 for regular and 0.6 for prn drugs). The reduction was most pronounced for the regular use of antipsychotics, antidepressants, hypnotics/sedatives, diuretics, antithrombotic agents, antacid drugs; and for prn use of anxiolytics, opioids, hypnotics/sedatives, metoclopramide and NSAIDs.

Conclusion: The medication review resulted in less drug use, especially opioids and psychotropic drugs.     

Palliative care presentations to emergency departments in a secondary and a sub-acute hospital: A one year incidence study

Introduction: There is growing concern that Emergency Departments (ED) are ill equipped to manage rising palliative care demand, but actual demand is unknown. The aim of this study was to estimate the annual incidence of patients with palliative care need presenting to EDs.

Methods: Retrospective case review study across two New Zealand emergency departments from 1 July 2010 to 30 June 2011. We used a two-step process where (1) administrative databases were screened for patients who had presented with 12 diseases associated with palliative care need and (2) the Gold Standard Framework Prognostic Indicator Guidance (GSF PIG) criteria were applied to the clinical records of a random sample of patients meeting the disease criterion.

Results: Fifty-three thousand and fifty-seven patients presented to the EDs; 4488 (8.5%) patients had diagnostic codes indicating potential palliative care need and 1024 were randomly sampled. One hundred and eighty-eight patients (18.4%, 95%CI 16.0–20.8%) from the random sample were identified as meeting GSF PIG criteria for palliative care need. The leading diseases were cancer (26.1%), COPD (26.1%) and heart failure (22.9%). Extrapolating from the estimated incidence, 826 of the 4488 patients with 12 diseases would have met GSF PIG criteria, suggesting only 1.6% of all patients presenting to ED meet GSF PIG criteria.

Conclusions: The incidence of patients with actual palliative care need presenting to EDs was lower than anticipated. Further research is needed to examine for secular trends in palliative care presentations and if the incidence rates are consistent in across ED settings.     

The rise and fall of the Liverpool care pathway

Introduction: The Liverpool care pathway (LCP) was created to aid in the delivery of high-quality palliative care across myriad healthcare providers. After high-profile criticism of the pathway and a subsequent inquiry its use was suspended in the United Kingdom.

Objective: The aim of this article is to systematically summarize the conditions leading to the rise and fall of the pathway. The authors also summarize the latest trials, which may point to a beneficial role of the pathway across diverse international settings.

Methods: We comprehensively search PubMed, Embase, and Cochrane databases for articles on the use of the LCP from 1997 to present. Keywords ‘LCP,’ ‘Liverpool care pathway,’ and ‘palliative care pathway’ were used. Reference lists of included articles were also assessed for relevant articles.

Results: There are two systematic reviews to date with no papers meeting criteria for inclusion. Several studies reported improvements in nausea and breathlessness when using the LCP. One comparative study found the use of the LCP was associated with a reduction in blood tests and radiological investigations with an increase in symptom assessment and palliative medication.

Conclusion: There is evidence supporting the on-going use of the LCP in countries other than the UK. Research is challenging in this population and more, well-constructed studies are needed to explore the use of care pathways at the end of life. Further guidance and documentation on communication with patients and their families at the end of life should be considered a priority for development.
