Burden of Palliative Care in a Public General Hospital Setting

ABSTRACT Objective: The number of palliative care patients in Trinidad and Tobago is unknown. The purpose of this study is to estimate the prevalence of palliative care patients on a public general medical ward. Methods: A retrospective cross-sectional study was undertaken to collect information on patients' diagnoses, symptoms and Palliative Performance Scale (PPS) scores. Patients who would benefit from palliative care services and satisfied inclusion criteria were referred to as palliative-care-appropriate patients. Results: The one-month prevalence of palliative-care-appropriate patients was found to be 23.47% on an acute medical ward of a public hospital. Most of these patients had diagnoses that were either neurologic or cardiac in nature. Pain (46.8%) and dyspnoea (51.1%) were the most common symptoms documented for palliative-care-appropriate patients. Seven (14.95%) palliative-care-appropriate patients died while in hospital. Conclusion: There is a significant palliative care burden in this pilot study as evidenced by the high prevalence of palliative-care-appropriate patients on a general medicine ward. A larger prospective study should be undertaken to elucidate the number of patients who could benefit from hospice and palliative care services. Palliative performance scale scores may be considered for more widespread use in the Caribbean.

Time course of training-induced microcirculatory changes and of vegf expression in skeletal muscles of spontaneously hypertensive female rats

Exercise-induced vessel changes modulate arterial pressure (AP) in male spontaneously hypertensive rats (SHR). Vascular endothelial growth factor (VEGF) is important for angiogenesis of skeletal muscle. The present study evaluated the time course of VEGF and angiogenesis after short- and long-term exercise training of female SHR and Wistar Kyoto (WKY) rats, 8-9 weeks (200-250 g). Rats were allocated to daily training or remained sedentary for 3 days (N = 23) or 13 weeks (N = 23). After training, the carotid artery was catheterized for AP measurements. Locomotor (tibialis anterior and gracilis) and non-locomotor skeletal muscles (temporalis) were harvested and prepared for histologic and protein expression analyses. Training increased treadmill performance by all groups (SHR = 28 percent, WKY = 64 percent, 3 days) and (SHR = 141 percent, WKY = 122 percent, 13 weeks). SHR had higher values of AP than WKY (174 ± 4 vs 111 ± 2 mmHg) that were not altered by training. Three days of running increased VEGF expression (SHR = 28 percent, WKY = 36 percent) simultaneously with an increase in capillary-to-fiber ratio in gracilis muscle (SHR = 19 percent, WKY = 15 percent). In contrast, 13 weeks of training increased gracilis capillary-to-fiber ratio (SHR = 18 percent, WKY = 19 percent), without simultaneous changes in VEGF expression. Training did not change VEGF expression and capillarity of temporalis muscle. We conclude that training stimulates time- and tissue-dependent VEGF protein expression, independent of pressure levels. VEGF triggers angiogenesis in locomotor skeletal muscle shortly after the exercise starts, but is not involved in the maintenance of capillarity after long-term exercise in female rats.

An audit of structure, process and outcome of care of the diabetic clinic, National Hospital of Sri Lanka.

AIMS: To audit the structure, process and outcome of care. SETTING: The diabetic clinic, National of Hospital Sri Lanka (NHSL). METHODS: A previously validated MCQ paper of 10 questions which assessed knowledge of diabetes on insulin therapy, dietary management, management during acute illness and management of emergencies was administered to all patients. The function of the clinic was assessed using previously validated audit case record forms. MEASURES OF OUTCOME: Diabetes knowledge among patients, waiting times, bypassing of local institutions, availability of diagnostic equipment, screening activities and time spent for consultation. RESULTS: The clinic had a daily average attendance of 186 patients seen between 0800 to 1200 hours. A single medical officer spent 2.1 minutes for each patient. No screening was performed. There were no facilities to examine patients or for them to sit during consultation. The diabetes knowledge score was 15.1 (SD 3) from a maximum score of 40.43% had bypassed a local institution. Reasons for bypass included non-availability of drugs and the expectation of quality care at NHSL. Patients spent a mean of 1.5 (SD 0.7) hours travelling to the clinic and waited a mean of 1.56 (SD 0.4) hours to see the doctor and 1.3, (SD 0.12) hours to obtain drugs. CONCLUSIONS: The services of the diabetic clinic do not meet the standards expected of a clinic at a tertiary referral centre. Lack of planning and resources (space, manpower and management skills) can be identified as principal shortcomings.
