Care related pain in hospitalized patients: A cross‐sectional study

Context: Care‐related pain includes pain occurring during transportation, movement, diagnostic imaging, physical examination, or treatment. Its prevalence has never been assessed in a large adult inpatient population. Objective: To identify the procedures likely to induce or increase pain in hospital patients, attempting to separate the most painful from those reported as most frequently inducing pain. Design: A single‐day cross‐sectional survey conducted in two large French teaching hospitals, including all hospitalized patients, free of communication problems. One third was randomly selected and interviewed about the painful episodes that had occurred or were associated with the procedures performed during the previous two weeks. Patients were interviewed using a structured questionnaire. Results: Six‐hundred‐eighty‐four patients were randomly selected. Six‐hundred‐seventy‐one painful events were reported in 55% of the patients, with an average of 1.8events/patient. Fifty‐two percent of the painful events were associated with procedures performed by non‐medical staff; 38% of the painful episodes occurred during procedures involving vascular puncture and 24% during patients’ mobilization. In 57% of painful procedures, pain was rated as severe or extremely severe. The most painful procedures were invasive procedures, other than vascular and non vascular punctures (74% of severe and extremely severe painful episodes). Maximum pain intensity was rated higher for procedures that were repeated than for those experienced only once (62% versus 53%, p=0.02). Conclusion: This survey gives new insight into our daily practice. Proper management of care‐related pain should be a major concern of all hospital staff to improve the quality of our health care.     

Ocular perfusion pressure and choroidal thickness in eyes with polypoidal choroidal vasculopathy,wet-age-related macular degeneration,and normals

Purpose

To measure the choroidal thickness and ocular perfusion pressure in eyes with polypoidal choroidal vasculopathy (PCV), wet-age-related macular degeneration (AMD), and age-matched normal subjects, and look for a possible association between the two.

Methods

This was a prospective study including 22 eyes with PCV, 33 eyes with wet-AMD, and 35 age-matched normal eyes. Choroidal thickness was measured using enhanced depth imaging (EDI) with spectral-domain optical coherence tomography (SD OCT). Mean ocular perfusion pressure (MOPP) was calculated using the mathematical formula 2/3[DBP+1/3{SBP × DBP}]−IOP (DBP—diastolic blood pressure, SBP—systolic blood pressure, IOP—intraocular pressure). Analyses were carried out using SPSS 14 software and comparisons of mean made using‘t'' tests.

Results

Eyes with PCV showed increased (285.9 μm; subfoveal) choroidal thickness, whereas eyes with wet-AMD (119.4 μm; subfoveal) showed reduced choroidal thickness in comparison with normal eyes (186.77 μm; subfoveal). MOPP in the PCV group was 57.85 mm Hg (P value 0.00), in the wet-AMD group was 52.1 mm Hg (P-value 0.12), and in the normal group was 49.79 mm Hg.

Conclusion

It is postulated that higher MOPP in eyes with PCV could have an etiologic implication in disease manifestation and progression. Larger studies with longer follow-up may help validate these findings.     

Serum glutathione-S-transferase and glutathione reductase activity in head and neck cancer patients

Glutathione, an antioxidant plays an important role in phase-II detoxification of carcinogens. The levels of reduced glutathione are maintained by glutathione-depleting as well as replenishing enzymes such as glutathione-s-transferase (GST) and glutathione reductase (GR), respectively. Pre and post treatment changes in GST and GR activities in head and neck cancer patients were analysed. Serum GST and GR were analysed from untreated head and neck cancer patients (PT) (n=146), controls with habit of tobacco (VHT) (n=25) as well as without (no) habit of tobacco (NHT) (n=25) and patients with oral precancerous conditions (OPC) (n=50). The cancer patients were followed-up after initiation of anticancer therapy. Follow-up blood samples were collected. Serum GST and GR activities were estimated by highly sensitive and specific spectrophotometric methods. Untreated cancer patients showed elevated mean serum GST and GR activities as compared to NHT. Patients with OPC had declined mean GST activity as compared to WHT and untreated cancer patients. Paired t-test revealed that complete responders (CR) showed significantly elevated GST levels and declined GR activities (p < 0.001) as compared to those in PT. No correlation was found between stage of the disease and GST, GR activity. Paired t-test showed significant decreased in GR activity in nonresponders (NR) treated with radiotherapy (p=0.01). The study suggested that analysis of glutathione and glutathione-depleting enzymes can be helpful for treatment monitoring of head and neck cancer patients.     

Anti-GBM nephritis in the mouse: severe proteinuria in the heterologous phase

Summary Highly reproducible anti glomerular basement membrane (GBM) nephritis has been induced in the mouse after a single injection of rabbit or goat antibody against purified homologous GBM. The severity of albuminuria was closely related to the amount of antibody given. With doses of 4 mg or more, low serum albumin concentrations, sometimes accompanied by ascites and oedema, were observed after 1 week. Glomerular injury was characterized by an initial accumulation of polymorphonuclear granulocytes followed by thrombosis and necrosis, the extent of which defined the outcome of the glomerulonephritis. With high doses of antibody the exudative lesions entered a chronic phase, while at doses lower than 2 mg remission of the lesions occurred. Immunofluorescence studies showed prompt linear fixation of the injected anti-bodies to the glomerular capillary wall, accompanied by immediate binding of C3 in a fine granular pattern. Fibrin deposits appeared at 2 h in some glomeruli, increased thereafter, and were present after one day in more than 90% of the glomeruli in mice that had received 4 mg of antibody. This new reproducible model in the mouse is suited for the study of the relationship between activation of mediator systems, histological lesions, and proteinuria.     

A prospective study of patients absconding from a general hospital psychiatry unit in a developing country

Characteristics of patients absconding from an open psychiatry ward in a developing country may be different from both those in developed countries and a mental hospital setting. The aim of this paper is to study the incidence and characteristics of patients absconding from an open psychiatric ward in a general hospital-based psychiatric unit in India. We studied patients consecutively admitted to an open psychiatric ward over a 2-month period. We compared those who absconded with those who did not. Out of 231 patients admitted, 33 absconded. Among those who absconded, 15 had bipolar disorder, 11 had schizophrenia and five had substance-related disorders. Nine had indicated their intention to do so at admission. Ten patients had absconded by the second day. The treatment cost was the likely influencing factor for seven patients who absconded after deemed fit for discharge on clinical grounds. Only 10 patients were readmitted to the hospital within 2 weeks of absconding. The risk of absconding is highest in the early days following. Absconding patients did not differ significantly from others in many socio-demographic and clinical features. Treatment costs are an important consideration in India.     

Patient preferences for coronary artery bypass graft surgery or percutaneous intervention in multivessel coronary artery disease

Objectives: Determine if patients prefer multivessel percutaneous coronary intervention (mv‐PCI) over coronary artery bypass graft surgery (CABG) for treatment of symptomatic multivessel coronary artery disease (mv‐CAD) despite high 1‐year risk. Background: Patient risk perception and preference for CABG or mv‐PCI to treat medically refractory mv‐CAD are poorly understood. We hypothesize that patients prefer mv‐PCI instead of CABG even when quoted high mv‐PCI risk. Methods: 585 patients and 31 physicians were presented standardized questionnaires with a hypothetical scenario describing chest pain and medically refractory mv‐CAD. CABG or mv‐PCI was presented as treatment options. Risk scenarios included variable 1‐year risks of death, stroke, and repeat procedures for mv‐PCI and fixed risks for CABG. Participants indicated their preference of revascularization method based on the presented risks. We calculated the odds that patients or physicians would favor mv‐PCI over CABG across a range of quoted risks of death, stroke, and repeat procedures. Results: For nearly all quoted risks, patients preferred mv‐PCI over CABG, even when the risk of death was double the risk with CABG or the risk of repeat procedures was more than three times that for CABG (P < 0.0001). Compared to patients, physicians chose mv‐PCI less often than CABG as the risk of death and repeat procedures increased (P < 0.001 and P = 0.004, respectively). Conclusion: Patients favor mv‐PCI over CABG to treat mv‐CAD, even if 1‐year risks of death and repeat procedures far exceed risk with CABG. Physicians are more influenced by actual risk and prefer mv‐PCI less than patients despite similarly quoted 1‐year risks. © 2013 Wiley Periodicals, Inc.
