Analisis Triwulanan: Perkembangan Moneter, Perbankan dan Sistem Pembayaran, Triwulan I - 2015

Pertumbuhan ekonomi pada triwulan I 2015 mengalami perlambatan, namun stabilitas makroekonomi dan sistem keuangan tetap terjaga. Perlambatan ekonomi bersumber dari melambatnya kinerja beberapa komponen permintaan domestik, seperti konsumsi pemerintah dan investasi bangunan. Sementara di sisi ekternal, ekspor masih melemah. Di sisi lain, stabilitas makroekonomi masih terjaga yang ditunjukkan dengan defisit transaksi berjalan yang menurun dan inflasi yang terkendali. Sementara itu, nilai tukar relatif terkendali meskipun mengalami tekanan

QUARTERLY OUTLOOK ON MONETARY, BANKING, AND PAYMENT SYSTEM IN INDONESIA: QUARTER I, 2016

The growth of domestic economy in Indonesia is lower than forecasted in first quarter of 2016.However, the economy is expected to revive and will grow higher in the next quarter, with a well maintained financial system stability. The limited growth of government consumption as well as private investment are the main reason for the slower growth in this quarter, eventhough the government spending on capital goods accelerates. The growth of private consumption remains high with reasonable price movement. With the increase of several commodities’ export, the external performance of export in aggregate also increased. On the other hand, the financial system stability was stable due to viable banking system and better financial market performance. The stability of Rupiah was well maintained, supported by positive expectation on domestic economy and the lower risk of the global financial market

QUARTERLY OUTLOOK ON MONETARY, BANKING, AND PAYMENT SYSTEM IN INDONESIA: QUARTER II, 2015

This paper provides current analysis of the ongoing quarter, and brief outlook on the forthcoming quarter. We use a field survey along with estimation of macroeconomic models to provide the assessment and to make some projections on the monetary, the banking, and the payment system in Indonesia. This paper confirms the slowdown of the Indonesian economy during quarter two 2015 due to the slowing investment and the government expenditure, and the weak export performance. With the fiscal stimulus launched by the government, we expect to see an improvement in next two quarters. The lower current account deficit and manageable inflation will help to maintain the macroeconomic stability; however, the high global uncertainty will put depreciation pressure on Rupiah

QUARTERLY OUTLOOK ON MONETARY, BANKING, AND PAYMENT SYSTEM IN INDONESIA: QUARTER III, 2016

The growth of Indonesian economy on Quarter III, 2016 recorded positive growth with a wellmaintained financial system and macroeconomic stability. The economy grew moderately supported by remaining strong domestic demand amidst the slow recovery of the global economy. The economic stability is also good reflected on the low inflation, decreasing current account deficit, and relatively stable exchange rate. An increase of domestic economy and lower global financial risk enable monetary ease on Quarter III, 2016. Furthermore, the reduction of interest rate policy is well transmitted and is expected to strengthen the growth momentum of the economy. Looking forward, Bank Indonesia will keep strengthening his policy mix and macroprudential, and his coordination with the government to ensure the inflation control, greater stimulus for growth, and the implementation of structural reform run on the right track, and hence preserve the sustainable economic development

Laparoscopy in management of appendicitis in high-, middle-, and low-income countries: a multicenter, prospective, cohort study.

BACKGROUND: Appendicitis is the most common abdominal surgical emergency worldwide. Differences between high- and low-income settings in the availability of laparoscopic appendectomy, alternative management choices, and outcomes are poorly described. The aim was to identify variation in surgical management and outcomes of appendicitis within low-, middle-, and high-Human Development Index (HDI) countries worldwide. METHODS: This is a multicenter, international prospective cohort study. Consecutive sampling of patients undergoing emergency appendectomy over 6 months was conducted. Follow-up lasted 30 days. RESULTS: 4546 patients from 52 countries underwent appendectomy (2499 high-, 1540 middle-, and 507 low-HDI groups). Surgical site infection (SSI) rates were higher in low-HDI (OR 2.57, 95% CI 1.33-4.99, p = 0.005) but not middle-HDI countries (OR 1.38, 95% CI 0.76-2.52, p = 0.291), compared with high-HDI countries after adjustment. A laparoscopic approach was common in high-HDI countries (1693/2499, 67.7%), but infrequent in low-HDI (41/507, 8.1%) and middle-HDI (132/1540, 8.6%) groups. After accounting for case-mix, laparoscopy was still associated with fewer overall complications (OR 0.55, 95% CI 0.42-0.71, p < 0.001) and SSIs (OR 0.22, 95% CI 0.14-0.33, p < 0.001). In propensity-score matched groups within low-/middle-HDI countries, laparoscopy was still associated with fewer overall complications (OR 0.23 95% CI 0.11-0.44) and SSI (OR 0.21 95% CI 0.09-0.45). CONCLUSION: A laparoscopic approach is associated with better outcomes and availability appears to differ by country HDI. Despite the profound clinical, operational, and financial barriers to its widespread introduction, laparoscopy could significantly improve outcomes for patients in low-resource environments.

Prognostic model to predict postoperative acute kidney injury in patients undergoing major gastrointestinal surgery based on a national prospective observational cohort study.

Background: Acute illness, existing co-morbidities and surgical stress response can all contribute to postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. The aim of this study was prospectively to develop a pragmatic prognostic model to stratify patients according to risk of developing AKI after major gastrointestinal surgery. Methods: This prospective multicentre cohort study included consecutive adults undergoing elective or emergency gastrointestinal resection, liver resection or stoma reversal in 2-week blocks over a continuous 3-month period. The primary outcome was the rate of AKI within 7 days of surgery. Bootstrap stability was used to select clinically plausible risk factors into the model. Internal model validation was carried out by bootstrap validation. Results: A total of 4544 patients were included across 173 centres in the UK and Ireland. The overall rate of AKI was 14·2 per cent (646 of 4544) and the 30-day mortality rate was 1·8 per cent (84 of 4544). Stage 1 AKI was significantly associated with 30-day mortality (unadjusted odds ratio 7·61, 95 per cent c.i. 4·49 to 12·90; P < 0·001), with increasing odds of death with each AKI stage. Six variables were selected for inclusion in the prognostic model: age, sex, ASA grade, preoperative estimated glomerular filtration rate, planned open surgery and preoperative use of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. Internal validation demonstrated good model discrimination (c-statistic 0·65). Discussion: Following major gastrointestinal surgery, AKI occurred in one in seven patients. This preoperative prognostic model identified patients at high risk of postoperative AKI. Validation in an independent data set is required to ensure generalizability
