Paediatric palliative care at home: a single centre’s experience

INTRODUCTION

There is increased awareness of paediatric palliative care in Malaysia, but no local published data on home care services. We aimed to describe the paediatric experience at Hospis Malaysia, a community-based palliative care provider in Malaysia.

METHODS

We conducted a retrospective case note review of patients aged up to 21 years who were referred to Hospis Malaysia from 2009 to 2013.

RESULTS

A total of 137 patients (92 male, 45 female) with a median age of 140 (3–250) months were included in this study. The majority (71.5%) had malignancies. At referral, 62 patients were still in hospital and 17 died prior to discharge. A total of 108 patients received home visits. At the first home visit, 89.8% of patients had at least one physical symptom. Pain was the most common (52.5%) symptom. Patients had various supportive devices: 39 were on feeding tubes, ten had tracheostomies, five were on bilevel positive airway pressure and ten had urinary catheters. 66 families discussed the preferred location of care at end-of-life. Among those who died, 78.9% died at home, as they preferred (p < 0.001). Regression analysis showed no statistically significant association between a home death and age, diagnosis and number of home visits. Bereavement follow-up occurred for 93.3% of families.

CONCLUSION

Community care referrals tend to occur late, with 25.5% of patients dying within two weeks of referral. At referral, patients often had untreated physical symptoms. The majority of families preferred and had a home death.     

ACS合并AHF患者治疗中RAAS抑制剂对CI-AKI发病的影响

目的 探讨肾素血管紧张素醛固酮系统（RAAS）抑制剂在急性冠状动脉综合征（ACS）合并急性心力衰竭（AHF）患者经皮冠状动脉介入术（PCI）中对比剂致急性肾损伤（CI-AKI）中的作用。方法 回顾性分析成功行PCI手术ACS合并AHF患者504例,并于术后24～48 h内复查肾功能。分别按照有无CI-AKI及有无应用RAAS抑制剂进行分组,对比相关观察指标,并将差异有统计学意义的观察指标进行Logistics回归分析。结果 504例患者中144例（28.6%）患者发生CI-AKI。CI-AKI组RAAS抑制剂使用比例、高血压、糖尿病患病率与非CI-AKI组比较,差异有统计学意义（P?<0.05）。CI-AKI组反映心脏功能超声指标LVEF、LVEDD、PAP、NT-proBNP、hs-CRP及Hcy水平与非CI-AKI组比较,差异有统计学意义（P?<0.05）。将上述指标引入Logistic回归分析发现,应用RAAS抑制剂对CI-AKI影响消失。而高血压、NT-proBNP、Hcy、hs-CRP、LVEF、PAP仍为心力衰竭患者CI-AKI发生高危因素。结论 对ACS合并AHF患者需行PCI治疗患者,常规应用RAAS抑制剂并不增加CI-AKI发生风险。     

Sleep deprivation and fatigue in early postpartum and their association with postpartum depression in primiparas intending to establish breastfeeding

Objective: To examine the association of objective sleep and fatigue in the early postpartum period with postpartum depression in Japanese primiparas intending to establish breastfeeding.Materials and Methods: The participants were 34 primiparas who were in the postnatal ward after vaginal delivery and responsively breastfeeding their rooming-in baby. Actigraphy data for objective sleep were collected for three consecutive days starting from the first day postpartum. Fatigue and postpartum depression were assessed using the Postpartum Fatigue Scale and Edinburgh Postnatal Depression Scale, respectively, on numerous days between the first day postpartum and the one-month checkup. Breastfeeding and rooming-in data were also collected.Results: The mean total sleep time was 252.0 ± 73.1 min/day. Mean breastfeeding frequency was 12.4 ± 3.2 times/day and mean total breastfeeding time was 247.4 ± 101.8 min/day. Among the participants, 67.6% were exclusively breastfeeding on the discharge day. Fatigue scores were significantly higher during the hospital stay, compared with one month postpartum. Multiple regression analysis showed that sleep frequency on the third day postpartum and mean total breastfeeding time and fatigue on the fifth day postpartum were factors affecting the Edinburgh Postnatal Depression Scale score.Conclusion: The association between postpartum depression among breastfeeding primiparas in the early postpartum period and objective sleep, fatigue, and total breastfeeding time per day was suggested. An environment wherein breastfeeding mothers can rest and sleep without hesitation will be beneficial. Moreover, the importance of sleep during pregnancy and the early postpartum period must be highlighted. Midwifery and/or nursing care starting while the mother is in a postnatal hospital stay can play a key role in preventing postpartum depression.
